Diamond Hollow

Diamond Hollow is a precision tracing game set in a luxury gem atelier. Each rough stone arrives etched with glowing laser cut lines. Touch the start point and glide along every groove: drifting off the line scratches the surface, and uneven speed chips sharp corners. Finish all lines before the timer ends to reveal a clarity grade from FL down to SI and turn carats into coins. Spend coins in the Workshop on laser skins, a steady tray, a loupe lens and a polish cloth, then take on harder stones with tighter arcs, sharp turns and narrow valleys.
